The Central Mechanical Engineering Research Institute (CSIR-CMERI) has set up a solar tree at the CSIR-CMERI residential colony in Durgapur, West Bengal. This is the largest solar tree across the world, with a capacity of over 11.5 kWp. Each tree is made up of 35 solar panels, each with a capacity of 330 W. The tree is capable of generating 12,000 to 14,000 kWh of electric power during a year. Each solar tree will cost Rs 750,000. The inclination of the arms holding the PV modules are flexible and can be adjusted. This feature is not available in rooftop solar systems.The solar trees can be aligned with agriculture for substituting price-volatile fossil fuels. Each solar tree has the potential to save 10-12 tons of carbon emissions when compared with fossil fuel, and the surplus power generated can be fed to the power grid.
